WebDissolved oxygen levels in sections of the river in which plants are the major contributor of oxygen fall sharply at night because photosynthesis ceases. In the Cuyahoga, dissolved oxygen levels in one study of fourteen sites ranged from 1.5 to 90 percent saturation, with an average of 13.2 percent. 100 percent saturation is most desirable. WebThe optimum pH levels for fish are from 6.5 to 9.0. Outside of optimum ranges, organisms can become stressed or die. As pH levels move away from this range (up or down) it can stress animal systems and reduce hatching and survival rates. The further outside of the optimum pH range a value is, the higher the mortality rates.
